The electronic structure of the aqueous permanganate ion: aqueous-phase energetics and molecular bonding studied using liquid jet photoelectron spectroscopy

Abstract

Liquid-jet photoelectron spectroscopy revealed the electronic structure of MnO4−(aq), O-ligand–water interactions, and aqueous-phase energetics of MnO4−(aq)/MnO4˙(aq.).

Probing the molecular structure of aqueous triiodide via X-ray photoelectron spectroscopy and correlated electron phenomena

“…22,23 Associated non-resonant and resonant core-level XPS experiments allow atomic bonding interactions, charge states, and core-valence and valence-valence electronic couplings to be selectively probed. [23][24][25][26] Using energytunable soft X-ray light sources, electron kinetic energies (KEs) and experimental probing depths can be continuously varied. 27,28 At electron KEs close to 100 eV, liquid microjet photoemission can correspondingly be applied to selectively investigate the liquid-gas interface.…”

Simulating the Feasibility of Using Liquid Micro-Jets for Determining Electron–Liquid Scattering Cross-Sections

“…Until now, applications of the aforementioned LµJ designs include an array of photoelectron spectroscopy experiments, to measure properties such as binding energies and hydrogen bonding [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. Other LµJ experiments include mass spectrometry [ 56 ], enhanced X-ray production [ 57 , 58 , 59 , 60 ], X-ray emission/absorption, to probe electronic structure and molecule orientation [ 61 , 62 , 63 ], to study the molecular dynamics of evaporation [ 64 ], electrokinetic power generation [ 65 , 66 ], and drug delivery alternatives [ 67 ].…”

“…A constant replenishment of liquid, a small surface area, and a laminar flow enable the scattering of particles from a smooth and stable liquid surface, whilst operating in a vacuum environment. Until now, LµJ investigations have focused primarily on photon and photoelectron scattering [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. In this work, we introduce electron scattering from LµJs and investigate the feasibility of developing effective electron–liquid cross-sections from the measured electron energy loss spectra (EELS).…”

Resonant X-ray photoelectron spectroscopy: identification of atomic contributions to valence states

“…60,61 Furthermore, RXPS has been used at the solidadsorbate interface. [62][63][64][65][66] More recently, RXPS has been used to study liquids, both for the solvent (water, 67 ILs 68,69 ) and more commonly for solutes in water (H 2 O 2 , 67 metal complexes [70][71][72][73][74][75] such as Fe 3+ in aqueous solution 70 and Ti 3+ in aqueous solution, 71 and nanoparticles 76,77 ).…”
